Nice summary article overall on personal medical monitoring. The security issue @aarunaku raises above is a concern but that is for anything that is wireless-connected with personal information, not just medical industry. The industry has been addressing this with various physical- and application-layer security measures.

If this is the case, will the health care going to cost less?
If the idea of smart monitor help tracing problems early and also reduce risks. It should definitely be helping to reduce trips to doctors/physicians/diagnostics, etc..
It should be similar to how emails replaced letters..
However, there could be a lot of scammers hopping into invade personal information, etc., and cost of maintenance of a smart device may be more than what it is intended to do.
Good luck with modernization without common sense.

In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
